so the other day my alarm went off (my fault) but the only problem is I cant find out how to stop it honking the horn once it goes off...I eventually just unplugged the battery from the car...im not sure what alarm it is it came with the car when I got it anyone know how I might turn it off if I set it off again?

Put the key into the outside door lock and everything should go off. It needs to know that you have the key and it's not stolen.
